This tool is a self-service API security scanner designed to surface risks before attackers do. Submit a URL and receive a risk score from A to F with prioritized findings. The scanner is black-box, requiring no agents, SDKs, or code access, and works across any language, framework, or cloud. All scans use read-only methods (GET and HEAD) plus text-only POST for LLM probes, complete in under a minute, and never modify endpoints.

The scanner evaluates 12 categories aligned to the OWASP API Top 10 (2023). It maps findings to PCI-DSS 4.0, SOC 2 Type II, and OWASP API Top 10 (2023), covering authentication bypass, JWT misconfigurations, broken object level authorization, privilege escalation, property over-exposure, input validation issues, rate limiting weaknesses, data exposure including PII and API keys, insecure transport, SSRF indicators, inventory and versioning gaps, and unsafe consumption surfaces. It also includes 18 LLM/AI security probes across Quick, Standard, and Deep scan tiers, testing for system prompt extraction, instruction override, jailbreak techniques, data exfiltration attempts, and token smuggling.

• Authentication — multi-method bypass, JWT alg=none, HS256, expired or missing claims, sensitive data in claims, security headers, WWW-Authenticate compliance.
• BOLA / IDOR — sequential ID enumeration and active adjacent-ID probing.
• BFLA / Privilege Escalation — admin endpoint probing and role/permission field leakage.
• Property Authorization — over-exposure, internal field leakage, mass-assignment surface.
• Input Validation — CORS wildcard with and without credentials, dangerous HTTP methods, debug endpoints.
• Rate Limiting & Resource Consumption — rate-limit header detection, oversized responses, unpaginated arrays.
• Data Exposure — PII patterns, Luhn-validated cards, context-aware SSN, API key formats, error/stack-trace leakage.
• Encryption — HTTPS redirect, HSTS, cookie flags, mixed content.
• SSRF — URL-accepting parameters and body fields, internal IP detection, active IP-bypass probes.
• Inventory Management — missing versioning, legacy path patterns, server fingerprinting.
• Unsafe Consumption — excessive third-party URLs, webhook/callback surface.
• LLM / AI Security — adversarial probes for prompt extraction, jailbreak, data exfiltration, token smuggling, and more.

The scanner parses OpenAPI 3.0, 3.1, and Swagger 2.0 documents with recursive $ref resolution. It cross-references spec definitions against runtime findings to highlight undefined security schemes, sensitive fields, deprecated operations, and missing pagination. For authenticated scans, support includes Bearer, API key, Basic auth, and cookies. Domain verification is enforced through DNS TXT records or an HTTP well-known file so that only the domain owner can scan with credentials. A strict header allowlist limits forwarded headers to Authorization, X-API-Key, Cookie, and X-Custom-*.

The Web Dashboard centralizes scans, report views, score trend tracking, and branded compliance PDF downloads. The CLI, provided as an npm package, enables scriptable scans with JSON or text output. A GitHub Action can gate CI/CD, failing builds when scores drop below a defined threshold. The MCP Server exposes scanning from AI coding assistants such as Claude and Cursor. For ongoing risk management, Pro tier offers scheduled rescans every 6 hours, daily, weekly, or monthly, diff detection across scans, email alerts rate-limited to one per hour per API, and HMAC-SHA256 signed webhooks that auto-disable after five consecutive failures.

Free tier provides three scans per month with CLI access. Starter at 99 dollars per month supports 15 APIs, monthly scans, dashboard, email alerts, and the MCP Server. Pro at 499 dollars per month covers 100 APIs with additional APIs billed at 7 dollars each, adding continuous monitoring, GitHub Action gates, CI/CD integration, Slack and Teams alerts, compliance reports, and signed webhooks. Enterprise at 2000 dollars per month offers unlimited APIs, custom rules, SSO, audit logs, SLA-backed support, and dedicated assistance. Scan data is deletable on demand and purged within 30 days of cancellation; customer data is never sold or used for model training.
